Incompatible Pressure Sensor Specifications

We occasionally receive requests for combinations of pressure sensor features that are not practical to include in the same specification. Below is a list of the most requested parameter combinations that are declined including explanations.

Low Pressure Range with High Media Temperature – the thin and large diameter diaphragms used in the construction of low range pressure sensors are more sensitive to thermal expansion which significantly effects sensor performance.

High Accuracy and Stability with High Media Temperature – some materials used in the construction of pressure sensing elements may out-gas, deform and become brittle when cycled to high temperatures causing an unpredictable change in sensor performance which limits the overall accuracy achievable.

Miniature Size with Low Range Pressures – a sensing diaphragm with a large surface area to thickness ratio is necessary for measuring low range pressures. A small size diaphragm is less sensitive to small changes in pressure due to its relatively low area to thickness ratio.

High Accuracy and Stability with Small Size – the design features included in the mechanical construction to facilitate precise and stable measurement take up additional space which is not available in smaller sensor packages.
